couple questions
well first off i know that the scts are the cream of the crop but i havent seen or heard much about the h&s performance tuners cause i like that its a tuner that has all the gauges and good stuff and i know that its a shift on the fly but i plan on leaving it on one tune that gets the best mpgs and so on, so if anyones got one or knows somebody that does id would appreciate the feedback. and second is exhaust, different strokes for different fokes my question is, is with the 6.0s the main killer is egts so would it be better for cooler egts to go with 5" or a 4" system?
